' application mea my e,

1 all whom t concern.'

.e it known that I, ALBERT L. Noms, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Rotay Brushes, of which the ollowing is a speci cation.

This invention relates to rotary brushes,

and it comprises a casing, a motor arranged in said casing, the main shaft of the motor projecting through the. end of the caslng,

a plate arranged thereon, a brush head' mounted on said plate, a cap arranged over handle for the purpose of ea a supportin -said shoulder. This plate is said brush head, and retaining means arranged 'on the end of the shaft.

In the resent invention, I have provided a motor riven rotary brush suitable for use in scrubbing clothes or in any other manner wherein a driven brush is desired. The brush is portable, whereby it may be moved over the surface of the cloth or other material being cleaned, and is provided with a manipulation.

A casingis provided for t e reception of the motor "ivvhereby the brush is driven and the brush is preferably arranged on the bottom of the, casing. The motor shaft extends through the bottom of the casingand `the brush is secured thereto.

In the preferred form of the' invention, the end of t'he motor shaft'pro'ecting from the casing is reduced to form a s oulder, and

' late is arranged on the rethe shaft for engagement with povided with duced end o an enlarged hub, vadapted to in a circular plate forming vthe A cap is arranged on the end of the shaft and secured to the retaining plate and brush head by any suitable means.

In vthe accompanying drawings, I have sllliloswsn'1 one embodiment of theinvention. -In t owin Figure 1 1s a plan view,

Figure 2 is a vertical sectional view of the casing and brush, the handle being shown in' elevation,

Figure 3 is a'. detail view of the handle and a portion -of the casing.

Fi e 4 is a. sectionalvrew on line of Figure 2, the lower end of the shaft and brush being shown irrse'ction,

Figure 5 is a detail sectional view on. line 5 5- of Figure 4 and, Figure 6 is a detail view ofthe brush. Referring to the' drawings, the refern received in P 1a1. semi no.v amiss.

numerall designates thecasing-which mayl be made of any suitable sha e and sze'and ,1 which is provided with a tu ular extension 2 for the reception'of a handle 3. As shown in Figure 3 of the drawings, the handle is provided with external threads 4 adapted extension for securing the handle in position. Lead wires 6 may be passed throu h the hanto engage internal threads 5 of the tubular dle which is preferably made o insulating material and connected toY contacts 7 carried by the handle and adapted to engage contacts '8 of the tubular extension when the handle is in position. A motor 9 of any suitable type 1s arranged within the casin the motor being provided with a main sha 10 supported 1n a bearing` 11, at its upper end and a bearing 12 at its lower end. The bearing 11 is formed integral with the motor casin and is provided with a threaded end for t e reception 'of a nut 13. The lower bearing is formed in a bottomgplate 14 vv'hich'- ing an oii'set portion 16. The bottom end o'f is provided with a peripheral iiange 15 havthe casing -is provided'with a ange 17 arranged adjacent the offset 16, and suitable fastening means 18 are vpassed through reg- 'i i istering'openings in the liange and oifset to retain the bottom plate in position. A .suit-l able control lever 19 is mounted on the tubular extension whereby the speed of the motor may be varied. vAs shown, a notched quad rant 20 is arranged adjacent the control lever. The main shaft of the motor extends beyond the bottom plate of, th'e casing and is rovided' with a reduced end 21 forming a shoulder 22. A supporting plate 23 is arranged on the end of the main shaft in engagement with the shoulder'22, the plate being keyed to the shaft by means of a key or pin 24, entering notches in the plate and shaft respectively (see Figures 4 and 5).

late is provided with' an enlarged central) portion 25 adapted to be received in an opening formed in the .base'plate 26 of the brush. A cap 27 is arranged under the hase plate, and suitable fastening elements 28 Aare passed through the cap, the base plate and the supporting plate to retain the parts in assembled position. The cap,base

material, having bristles 30 mounted therein. The baseplete is vfurther provided with the enge 15 of the bottom plete of the cies- Y ing to the brush. Y

By means of the oonstruction herein disclosed, e rotary brush is. provided in .which the partsare connected to each otherto permit movement of the brush from place to glace either during operationV or when the'. rush isnot being used. The means for re taining the brush on the motor. shaft permit Yreedy removal of the parts for the purpose of cleaning, replacing and repairing. In use, the brush may tre-vei over the surface of the material being cleaned in e manner similar to the manner in which an iron passes over the surface of goods in pressing. it is to be understood that the form of my invention herewith shown and described is to be teken as a preferred exemple of the same, and that various changes in the shape, size, and ngement of ports may be re sorted to without departing from the' spirit ofr the invention or the scope of the subjoined claims.

Having thus described my invention,- I claim:
